[Experimental investigations of electrolyte metabolism of the myocardium during coronary perfusion of isolated hearts of warm blooded animals with ionic, less ionic, and non-ionic contrast media. Part 5 (author's transl)].

In the isolated guinea pig heart the extracellular metabolism of Sodium, Potassium and Calcium after coronary perfusion of ionic, less ionic and non-ionic contrast media has been examined. Under these conditions there are not significant differences of the extracellular metabolism for these electrolytes. The results are controversial to those gained in the whole-body animal. The causes are being discussed. In clinical treatment better tolerance of the patients after the application of less ionic and non-ionic contrast media was observed during laevocardiography and coronarography.
